Embodiment 1

[0045] Embodiment 1 of the present invention provides a method for adjusting the backlight of a display screen, and this embodiment will be described in detail below with reference to the accompanying drawings.

[0046] figure 1 It is a schematic flow chart of Embodiment 1 of the present invention, please refer to figure 1 , the method of this embodiment includes the following steps:

[0047] S1. When the display system receives a request to turn on the screen, activate the light sensor; wherein activating the request to turn on the screen includes but is not limited to a phone call, a text message reminder, or pressing a power button;

[0048] S2. Collect the current ambient light intensity through the light sensor, report the collected ambient light intensity to the application layer, and judge whether the current ambient light intensity is the lowest intensity level; if it is judged to be yes, then enter step S3; if it is judged otherwise, enter step S2. S4;

[0049] S3....

Embodiment 2

[0061] Embodiment 2 of the present invention provides a method for adjusting the backlight of a display screen, which is an improvement on the basis of Embodiment 1. figure 2 It is the implementation flowchart of Embodiment 2 of the present invention, please refer to figure 2 , the method of the embodiment of the present invention includes the following steps:

[0062] S1. When the display system receives a request to turn on the screen, activate the light sensor; activating the request to turn on the screen includes but is not limited to a phone call, a text message reminder, or pressing a power button;

[0063] S2. Collect the current ambient light intensity through the light sensor, report the collected ambient light intensity to the application layer, and judge whether the current ambient light intensity is the lowest level intensity;

[0064] S3. If the current ambient light intensity is the lowest level, the application layer sets the backlight brightness of the displ...

Embodiment 3

[0092] Embodiment 3 of the present invention provides a system for adjusting the backlight of a display screen, image 3 It is a schematic block diagram of the structure of the system provided by Embodiment 3 of the present invention. The system includes:

[0093] The display screen detection unit 20 is used to detect the screen brightening request of the display screen, or the screen off request;

[0094] The light sensor 30, when the display screen detection unit 20 detects a bright screen request, automatically starts to collect the current ambient light intensity;

[0095]The first judging unit 40 is used to judge whether the current ambient light intensity collected by the light sensor 30 is the lowest level intensity;

[0096] The backlight brightness adjustment unit 50, when the first judging unit 40 judges that the current ambient light intensity is the lowest intensity level, sets the backlight brightness of the display screen to be the lowest brightness level, and ...

Abstract

The invention discloses a method and a system for adjusting display screen backlight and a mobile terminal. The method comprises the following steps that when a display system receives a screen lightening request, the current ambient light intensity is collected by a photo sensor, and whether the current ambient light intensity is the lowest intensity level or not is judged; if so, the backlight brightness of a display screen is set to the lowest brightness level, the backlight of the display screen is lighted up in a level-to-level manner until the backlight brightness of the display screen reaches the lowest brightness level; and if not, the backlight brightness required by the display screen is set according to the current ambient light intensity, and the backlight of the display screen is directly lighted up and set to the backlight brightness required by the current ambient light intensity. When the ambient light intensity is lower, the method and the system can realize that the backlight of the display screen is lighted up in a level-to-level manner, the eyes of a user can slowly adapt to the backlight brightness of the display screen, and the problems that the user suddenly sees the bright display screen in a dark environment to result in dazzling and uncomforting of eyes are avoided. The use experience of the user is optimized.

Description

technical field [0001] The invention relates to the technical field of mobile communication; in particular, it relates to a method, a system and a mobile terminal for adjusting the backlight of a display screen. Background technique [0002] In the prior art, the mobile terminal realizes intelligent adjustment of the brightness level of the backlight of the display screen by using a light sensor. The light sensor can sense the surrounding light conditions, and inform the processing chip to automatically adjust the brightness level of the backlight, thereby reducing the power consumption of the product and prolonging the working time of the battery to the greatest extent. When the ambient light intensity is weak, the backlight brightness level is low, and when the ambient light intensity is strong, the backlight brightness level is high. The light sensor collects the current ambient light intensity, and intelligently adjusts the brightness level of the backlight of the displ...
